egt temps

[nboeger4]

ok before i get thrashed for this question i already did a search and all i could find was a bunch of different information. i just got my egt guage hooked up the right way this time in the exhaust manifold and i was wondering whats the temp you need to start getting concerned about and if it stays there for how long? im going to be pulling a 8,000 lb boat tomorrow and i just dont wanna hurt the truck and im not used to pulling a load this heavy with my truck. also should the temp guage move up and down a lot? or stay in the same position? and one more thing whats a good temp to shut the truck down at 250 is what i think i remember reading awhile back.
thanks guys

1250 is getting to hot. Anything over that and you should start backing out of the throttle. Many guys have run 1500+ and were ok but that was for a split second and I wouldnt recommend it.

like i know tonight i went out and got on it a little bit to see what it would read and it hit 1400 but it didnt stay there very long. im taking 3 seconds maybe is that bad? if so how can i get the egts lower?

Yeah, the search feature is worthless on this site, its no problem though, most of us don't care if people ask instead of search, those that do care, tell them to f off. i just got my egt guage hooked up the right way this time in the exhaust manifold and i was wondering whats the temp you need to start getting concerned about and if it stays there for how long? 1250 is when you want to start being cautious. I have run mine up to over 1500, no idea what they really were, it was buried, and i've had no problems. I wouldn't recommend doing that, as mine was on accident, but you must heat soak the pistons to damage them, and there is oil cooling them down. I woundn't run it over 1250 for more than a few seconds. im going to be pulling a 8,000 lb boat tomorrow and i just dont wanna hurt the truck and im not used to pulling a load this heavy with my truck. You should be fine. are you chipped? what setting do you plan on towing in? 8K is nothing for these trucks. I would be more concerned about trans temps than EGT's also should the temp guage move up and down a lot? Yes, it will vary with load or stay in the same position? no, it will move a lot and one more thing whats a good temp to shut the truck down at 250 is what i think i remember reading awhile back. I usually wait till 300ish, if ive been running it hard i just wait about 3-5 minutes then shut it down.
thanks guys

IH, the people that make our motor say a Pre turbo red line of 1250 is fine. You can drive all day at 1250 and hurt nothing but your milage. Normal cruseing you should see about 600-700.

You can go over 1250 for short periods of time, its about heat soak. If the pistons have been seeing 600 all day, you can stay above 1250 longer then if you have been pulling all day at 1100... understand?
